Two opposite sides of the main body 10 are respectively connected to thefirst wing 30 and the second wing 40. The first wing 30 and the secondwing 40 can be connected to each other detachably, and the first wing30, the second wing 40, and the main body 10 enclose and form a firstholding space B. the extended piece 50 is connected to the main body 10,and is provided close to a bottom opening P1 or a top opening P2 of thefirst holding space B.

In this embodiment, the first wing 30 and the second wing 40 areconnected to each other through two fasteners 60 and two belts 62 on thefront side 10 b of the main body 10. Each of the belts 62 is providedbetween the first wing 30 and the second wing 40, and the length of eachof the belts 62 is adjustable. Therefore, the user can adjust thelengths of the belts 62 according to the size of the objects, andthereby change the volume of the first holding space B to meet theuser's needs. In other embodiments, the number of the fasteners and thebelts can be one or more than two correspondingly, and is not limited tobe two.

As shown in FIG. 2, the first wing 30 and the second wing 40respectively has a containing bag 64; the containing bags 64 arerespectively provided on the interior faces of the first wing 30 and thesecond wing 40 which face to the first holding space B. Thus, the firstwing 30 and the second wing 40 have not only the function of forming thefirst holding space B with the main body 10, but also the function ofstorage. Practically, the containing bag 64 can be only provided oneither the first wing 30 or the second wing 40, and is not limited to beprovided on both the first wing 30 and the second wing 40.

In this embodiment, the extended piece 50 has a first side 50 a and asecond side 50 b, wherein the first side 50 a includes a first connector52, and the second side 50 b is connected to a bottom 10 c of the mainbody 10. The first side 50 a of the extended piece 50 is detachablyconnected to the main body 10 by the first connector 52. Furthermore,the main body 10 includes a plurality of joint pieces 12 which aredisposed at intervals on the front side 10 b of the main body 10,wherein the joint pieces are arranged from the part close to the top 10d of the main body 10 to the part away from the top 10 d of the mainbody 10. The first connector 52 is detachably connected to one of thejoint pieces 12.
